SPARK-ARRESTER.

Specification of Letters Patent.

Patented Sept. 10, 1912.

To all whom it may concern:

Be it known that I, ANDREW WALTER GRAHAM, a citizen of the United States, residing at Bradford, in the county of Mc- Kean and State of Pennsylvania, have invented certain new and useful Improvements in Spark-Arresters, of which the following is a specification.

This invention relates to locomotives and has particular reference to a spark arrester such as is employed in the smoke box of engines of this character.

The principal object of the invention is to improve the general construction of devices of this description.

A second object of the invention is to provide a device of that character which will effectively break or pulverize the large cinders into such minute fragments that they will be readily consumed and extinguished before leaving the stack and thus be rendered incapable of doing harm by setting fire to combustibles adjacent the track.

' A third object of the invention is to pro.- vlide a device which will not be liable to 0 0g.

With the above and other objects in view the invention consists in general of certain novel features of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings like characters ofreference refer to like parts in the several views, and Figure 1 is a transverse section through the smoke box of a locomotive showing the device in position therein. Fig. 2 is a similar longitudinal section through such a smoke box. Fig. 3 is top plan view of the device. Fig. 4 is a section on the line 4-4 of Fig. 3 through one of the sections of the spark arrester. Fig. 5 is a cross section through a portion of one of the battle plates employed in this invention. Fig. 6 is a face view of such a plate. Fi .7 is a horizontal section on the line 77 of ig. 4.

In the drawings there is illustrated a boiler 10 of the type commonly employed in locomotives. This boiler has in front of the water compartment a smoke box 11 and nozzles 12 project upwardly in this smoke box and are connected with the exhaust from the cylinders of the engine which are not deemed necessary hereto be shown. Resting on these nozzles or connected therewith is a housing 13 of polygonal form by preference and secured to this housing preferably consisting of a flat plate having a depending peripheral flange 13 by any suitable means, as by the bolts 14 are members 15 radiating from the conjoining angles of which are plates 16 which are so arranged that the plates from one side of the polygonal housing contact with the plates of adj acent sides of the housing, the adjacent plates being secured by fastening means such as indicated bythe bolts 17. Each of these v the inner edges of the plates 16 are bridged by vertically spaced members 18 which are preferably made of sheet metal and punched to provide openings19 surrounded by out- "wardly projecting teeth 20. The spaces betweenthe members 16 are bridged bya plurality of series of spaced but interlocking S-shaped members 21 each provided with apertures 22 formed by striking the metal without the possibility of clogging the deflanges 26 and radial flanges 27, the latter I 1). 0.

CLOTHES-PRESSING MACHINE.

Specification of Letters Patent.

Application filed August 16, 1911. Serial No. 644,430.

thereon, which form a part of this specification.

This invention relates to new and useful improvements in clothes pressing machines.

The object of the invention is to provide a device of the above type which may be easily operated, in that the entire operation of pressing is accomplished by the movement of the foot.

Another object of the invention is to provide a device of this type by means of which more satisfactory results are obtained than by those machines hereto-fore employed.

The invention consists further in certain details and arrangements which will be more fully described in the specification and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a top plan View of the machine; Fig. 2 is a section on the line a-(z of Fig. 1; Fig. 3 is a front elevation with the base shown in section; and Fig. 4 is a section 011 the line b?) of Fig. 1, through the pressing head.

Referring more particularly to the draw ings, 1 represents a hollow base standard which supports a table 2. Mounted on the table 2 is a supporting member 3 which, in turnfsupports a pressing buck 5' upon which the clothes to be pressed are placed. Adapted to press against the buck 4, and the clothes thereon, is a pressing head 5. The head 5 is vertically and horizontally movable, and is adapted to be elevated and moved rearwardly to allow the clothes to be" placed on the buck, by the following mechanism. The head 5 is mounted on the forward arms 6 of a bifurcated lever 7 provided with elongated recesses 8 which receive a shaft 9 mounted'in brackets 10 extending from the base 1. The rear end of the lever 7 lies between a pin 11 on disks 12, and the upper oscillating end of a connecting rod 13 attached to the disks 12. The disks 12 are pivoted at 14 to brackets 15, and act as "guides for the lever 7 during the rearward of a foot lever 16' pivoted at 17 to the base 1,

and provided with a foot plate 18 at its other end, When the end of the foot lever carrying the foot plate is elevated, the upper end of the connecting rod 13 will rotate the disks 12 and depress the pin 11, thereby rocking the lever 7 on the pivot shaft 9 and elevating the pressing head 5. While being elevated, the head 5 is moved rearwardly' as follows. Mounted on the lever 7 is a rack 19 in mesh with a pinion 20 on the pivot shaft 9. The shaft 9 carries a sprocket 20* around which passes a chain 21. One end of the chain 21 is attached to a cable 22, which passes over a ShGfiNG 23 and is attached to a spring 24 connected to the base 1 at 25. The other end ofthe chain 21 is attached to a cable 26 which passes around sheaves 27 and is connected to-the foot lever 16 at 28. In the position the parts are shown -in the drawings, the spring 24 is exerting a force to elevate the lever 16 and to rotate the sprocket 20 and pinion 20; and when the lever 16 is released by the foot, the spring 24 will rotate the pinion 20 and move the lever 7 and pressing head 5 rearwardly. After the lever 16 has beenelevated, and is then depressed by the foot, the pinion 20 will then be rotated in the opposite direction and the pressing head 5 will move forward. During this operation of the lever 16, the head 5 will be depressed by the upper end of the connecting rod 13 engaging the rear end of the lever 7. When the pressure head 5 is in contact with the clothes on the buck 4, heat may be applied thereto by any suitable agency. However, I prefer the use of heated air under compression, which is applied as follows. Mounted within the base 1 is an air compressor 29 driven by a motor 30 and connected to an air tank 31 by a tube 32. Within the tank 31 is an electric heating coil 33 provided with leads 34, which may lead to any source of electric current. The air for heating the clothes is compressed within the tank 31, and the temperature thereofv is elevated by the coil 33. The tank'31 is connected with the pressure'head 5 by a tube 34, provided with a swivel joint 35 in alinement with the pivot shaft 9, and with a telescopic joint 36 which permits the head 5 to move without disturbing the tubular connection between the tank 31 and the head 5; The head 5 is hollow, and placed therein is a longitudinal perforated pipe 37 which connects with the tube 34. The longitudinal pipe 37 isprovided with perforations 38 which direct the air in minute jets against the garment on the buck 4. Connected to the tube 34 is a quick opening valve 39, actuated by a lever 40 and controlling the admission of the air to the interior of the head. The head 5 is provided with a wire screen 41 which disperses the air, and a pressing cloth 42, which are stretched across the bottom of the head and held in posit-ion by any suitable means such as clamping bands 43.

The operation of the device is as follows. Before the-machine is placedin operation, sufficiently heated air is compressed in the tank 31. The garment to be pressed is then placed on the buck 4, and the lever 16 de- This operation actupressed by the foot. ates the chain 21, which rotates the sprocket '20 and the pinion 20, and which moves the lever 7 and head 5 forward. During this operation, the upper end of the connecting rod 13 engages the lever 7 and moves the head 5 to a position to engage the garment on the buck, or that position shown in Fig. 2. The operator then opens the valve 39, which permits heated and compressed air from the tank 81 to come in contact with the garment on the buck. When the garment has been subjected to the pressure of the head 5 and the heated air, a sufficient length of time, the operator releases the lever 16, which permits the spring 24 to ele vate said lever. During this operation the pin 11 engages the lever 7 and elevates the head 5, and the chain 21 is actuated to r0- tate the sprocket 20 and the pinion 20 to move the lever 7 and head .5 rearwardly. When the head 5 is in its rearmost position, it is out of the way of the operator when adjusting the garment on the buck.

, It will be seen that a machine as thus constructed may be easily operated, as the entire movement of the head is controlled'by the foot. Also as heated compressed air is used as a heating medium, the garment will not be subjected to excessive moisture, which would not produce the best results and which has a damaging efiect on the garment. It will also be noted that the mechanism which carries the head provides for a suflicient space in the rear of the buck for the garment to be manipulated without crampingthe same. On the whole, the ma chine as constructed is compact and self contained and may be manipulated by unskilled persons.

Without limiting myself to the precise arrangement shown and described, which may be varied within the scope of the claims, I claim: y

1. In a device of the type specified, a pressing buck, a vertically and horizontally movable pressing head mounted above said buck, a sliding lever upon which said head is mounted, a gear adapted to move said lever horizontally, a chain adapted to rotate said'ge'ar, a resilient member to which I said chain is connected, a foot lever connected to said chain, disks mounted on e1ther side of said first named-lever and adapted to actuate the same, and connections between said foot lever and said disks.
